Common Causes of a Running Toilet

A running toilet is typically caused by a faulty flapper or flush valve, which can prevent water from properly exiting the tank and entering the bowl. The most typical causes of a running toilet are:

  • Faulty Flapper: The flapper is a rubber valve located at the bottom of the tank and is responsible for sealing the opening between the tank and the bowl. If the flapper is worn or damaged, water can leak from the tank into the bowl, causing the toilet to run.
  • Damaged Flush Valve: The flush valve is the mechanism that controls the flow of water from the tank into the bowl. If the flush valve is damaged, it can prevent water from correctly entering the bowl, causing the toilet to run.
  • Water Level: If the water status in the tank is set too high, it can cause water to flow constantly into the overflow tube, leading to a running toilet.

How to Fix a Running Toilet

If you’re experiencing a running toilet, follow these steps to fix the problem. Here’s a step-by-step guide to selecting a running toilet:

  • Step 1: Turn off the Water Supply
    Before you begin any repairs, turn off the water supply to the toilet. Then, look for the water valve behind the toilet and turn it clockwise until fully closed.
  • Step 2: Remove the Tank Lid
    Carefully remove the tank lid and set it aside in a safe place. Don’t drop it, as it can easily crack or break.
  • Step 3: Check the Flapper
    Inspect the flapper for any signs of wear or tear. If there is damage, it must be replaced. To replace the flapper, detach it from the chain and replace it with a new one.
  • Step 4: Adjust the Flush Valve
    If the flapper does not cause the problem, the flush valve may need to be adjusted. To adjust the flush valve, bend the float arm slightly downward to increase the water level in the tank.
  • Step 5: Check the Water Level
    If adjusting the flush valve doesn’t solve the problem, check the water level in the tank. The water level should be set about one inch below the top of the flood tube. You can adjust the float arm until the water level is at the correct height if the water level is too high. 
  • Step 6: Turn on the Water Supply
    Once you’ve made the necessary repairs, turn the water supply before on and flush the toilet a few times to ensure it works properly.
